ABSTRACT:
A combination wheelchair/walker when in a wheelchair configuration having four spaced apart surface support wheels positioned on each corner of a generally rectangular form in which a person is supported thereby. The rear pair of wheels fixed in their direction of travel and the front pair of wheels being pivotable through 360 degrees. In the walker configuration the generally rectangular form is converted into a generally triangular or trapezium support form with the two rear wheels remaining in their original spaced apart position with the front two wheels moved closer together in a relatively reduced spaced apart relationship acting effectively as slightly spaced apart dual wheels. The seat platform of the wheelchair is rigid and folds up against the front of the back of the device in its walker or transport/storage configuration. For storage the rigid seat folds up against the back, the sides of the wheelchair/walker fold inwardly against the back one side over the other in a minimum front to back dimension nesting relationship. A spring biased locking pin secures the sides in the three positions.
